D0 PMG February 15, 2001 Installation update View of collision hall Feb 14, 2001 Feb 6, 2001 Feb 9, 2001

D0 PMG February 15, 2001 Status Overview: SMT  Silicon u Silicon detector (SMT-S & SMT-N) s Installed s Infrastructure (cooling, air) u H-disks ( need 4) s 4 H disks installed u Infrastructure s Cooling system hooked up s More later under electronics

D0 PMG February 15, 2001 Fiber Tracker Status  Waveguide Production and QC continue at a very small scale; use less fiber ( $100K  $50K)  Installation Waveguides u South & North: done  VLPC cassettes Goal (99): projection was Feb 26, 2001 now mid March, due to AFE testing 91 fabricated, 87 characterized, 12 more ready for DØ

D0 PMG February 15, 2001 Status Overview  Central Muons (94 PDT’s) u Commissioning continues u Triggering on tracks  Forward Muon detectors u All commissioned, except B layer pixels; u C layer pixels to finish ( timing)  Gas systems (recircl. & clean) u Being installed LayerPixelsMDT’s A North & South: done North & South: done B North & South: done North & South: done C North & South: done Installation status

D0 PMG February 15, 2001 Status Overview; Electronics  Electronics u Calorimeter s Preamp installation/commissioning underway (55k installed: all done, EN & CC power ready, cooling installed, ES going in) s BLS status –Motherboard: 1250/1200/1020 – need/bare/stuffed – ( no progress: 50/week; should 100/week) –Daughter cards 5000/5000/4220 –Daughter card: 300/week should; but none in last few weeks ( ORACLE SUNYSB ??) –CC, ECN were cold and filled with liquid; now empty –Have 4 out of 12 timing modules ( boards being assembled) s Have read out 4500 channels u Muon s Done

D0 PMG February 15, 2001 u Tracking Electronics s Si Interface Card –144 needed –All boards in hand –144-4 tested and ready s Adapter card –Done fabricating –& installed south side s Analog Front End boards –Remake the PCB’s (148)( second set) –Release Feb 19 –PCB status clear: remake !!! –Have 10 prototype boards –4 stuffed; 2 being tested –Tests look promising, but have to continue –Latest release date for stuffing March 19 s MCM going –At FNAL 2220; need 2200 s Power supplies –Being installed Status Overview; Electronics SMT Fiber tracker

D0 PMG February 15, 2001 Si Sensor To and from DAQ Description # need # have Location HDI with SVX --in SMT 8’ Low mass cables & clock cables H H SMT support cylinder to CC face Adapter card 144* 4 Installed on CC face ( 144*2) 19’-30’ High Mass Cable; 3M/80 Conductor & clock cables 144* 4 144*4 ( found all) ~288 (south) installed Interface card 144 east & west side of CC; going in 25’ High Mass; 3M/50 Conductor 144* 4 144*4 ( missing, reorder or spares) To sequencer; 3* 144 in SMT readout front end system status

D0 PMG February 15, 2001 Description # need # ready Location Waveguides from CFT (axial & stereo), CPS, FPS - CFT & CPS DONE From face of CC to platform VLPC cassettes9987platform AFE 8 with 8 MCM’s; readout axials & stereo 136 incr. 10 proto problem On VLPC cassttes MCM; multichip module with SIFT & SVX chip On AFE xx boards AFE 12 read out stereo, CPS, FPS 62 Progress design On VLPC cassettes Mixer boards (trig) 20 2 end of March; Prototyp es on way Digital part (trig) & arriving platform Fiber tracker readout front end system status DAQ AFE 8 VLPC AFE 12 VLPC CFT, CPS, FPS L1 Trig Infrastructure installed

D0 PMG February 15, 2001 Status Overview  Trigger u Final hardware arrival is a worry  Level1:  CFT trigger; digital parts arriving March  CAL few towers on March 1 & run; delivery in March  Muon ~2octants in central & 1 in each end; arriving in March & April  L2 VME-Alpha boards still a concern. Looking better: 25 produced; 3 partially working; 6 completely working. Expect another 2 to rise from dead.  Three approaches:  Effort in CD continues (THANKS)  Another production run. Have parts for 12 boards.  New design completely…..  L3 board production concern  Abandoned high speed SIB design on PCI card with high bandwidth IN and OUT  Goal now is to achieve 50 to ~150Hz in April  Two critical boards (SIB, VBDi). SIB have boards, VBDi going out  Online u In use at low rate, not on critical path

D0 PMG February 15, 2001Summary  Concerns u Installation: Mechanically complete u Electronics delays are THE concern for realistic commissioning with beam s Vendor delays, parts availability  Outlook u “Detector” will be ready for beam on March 1 u All detectors will be installed u Not completely hooked up u Limited data rate in DAQ ~few Hz u Will need TIME after start up to complete the detector electronically ( see later)
